Product Information

Gunson is the UK's most recognisable name in classic motoring tools — the brand behind the Eezibleed, the Colortune, and the Trakrite. If you've ever maintained a British classic, you've probably used a Gunson.

The Gunson Low Voltage Circuit Tester 6V - 48V - GPL (Part Number: GPL) is a genuine Gunson product, supplied through official UK distribution.

With the introduction of new mild-hybrid vehicle systems operating at 48 volts, Gunson has developed a simple voltage tester that is safe for use on these systems. The 77143 is easy to use and features red LEDs to indicate both the voltage level and the polarity of the current in the circuit being tested.

Features
  • Suitable for detecting voltage in wiring, terminals, etc, in low voltage applications including car & commercial vehicle electrical systems. Works with both negative & positive earth systems.
  • Lead length: 0.9m.
  • Specification: 6V - 48V.
  • Features a partially shrouded probe to reduce the potential for accidental shorting out.
  • No Batteries required, powered from the power source being measured. CE & UKCA compliant.
